“…Cook, Roll, and Kazakov (1990) and Roll, Cook, and Golany (1991) firstly proposed to use common weights for efficiency evaluation in DEA in the application background of performance evaluation and ranking of highway maintenance units. Further work on DEA common-weight evaluation can be seen in Kao and Hung (2005); Zohrehbandian et al (2010);and Sun et al (2013). There are still other methods for enhancing the discriminative power of DEA, such as the benchmarking ranking techniques (Sueyoshi, 1999;Lu & Lo, 2009;Sinuany-Stern, Mehrez, & Barboy, 1994), the multi-criteria decision-making methodologies (Li & Reeves, 1999;Strassert and Prato, 2002;Wang and Jiang, 2012), and the context-dependent DEA method (Seiford & Zhu, 2003;Chen, Morita, & Zhu, 2005).…”
